Ford F-150 (2009-2014) :: STX With Pulsating Sucking Sound When Cold
Nov 10, 2012
2009 F150 STX with 4.6L 3 valve engine. When first started there is a pulsating sucking noise (sounds like a small vacuum pump at where I work) that has started to come from under the hood. Only does this for about 10 seconds or so and then goes away. The colder the engine is when started the worse it is. I have also noticed that about 10 or so seconds after you shut the engine off you can hear a valve of some sort opening up and a rush of air. I think this is coming from the passenger side by the radiator. Where this sucking noise is coming from? And is this valve release at the end normal? The truck has about 48K miles on it so don't know if this would be a warranty thing or not.

What would cause a clicking sound when it is cold outside. When the temperature is -20 Celsius the truck makes a loud clicking sound upon acceleration. When the truck is at idle it goes away. When the truck warms up it goes away. What this might be?

I have a 2012 F-150 Platinum 6.2L. Every morning after a cold start, I get this humming sound until the engine heats up. It does seem to get a little quieter when I'm moving but not much. This only happens after the first start of the day and has only started doing this since it's been cold (20-30 F).

I have a 2012 F150 5.0 I just bought a couple weeks ago. I have a metallic ticking sound when cold, you can hear it when it idles down, but once driven and hot it is more faint but still there. Its not the injectors, Ive checked that.
Ive seen it posted in various forums but no cause mentioned. Ive had it in to the dealership and they are waiting for Ford to get back to them on what to do but I fear they will say its normal. My friends 2013 doesn't do it at all.
Listen to whole video, wait until the camera was placed on tire and its idled down to hear it. Its louder in real life but not extreme loud.

It seems that my 09 F150 has developed a troubling noise... I'm looking for any cam phaser. I'm at 116,712mi. 5.4L motor of course.
On cold start, I hear about 2 seconds of "clatter" - sounds like something is "loose" on top of the motor. At hot idle, I hear the classic "diesel" idle, indicative of the cam phaser issue. In gear, the rattle intensifies and is very noticeable around 1000RPM.
Other than the noises, the truck runs great - like new.
Here's a video: [URL] ....
Under hood, under hood close up, driver's wheel well, interior, then interior in gear. You'll need to crank the volume to hear the last two.
Best I can tell, this is not an exhaust manifold issue. So, what say you? Cam phasers?

5.0 coyote exhaust leak .. Since the cold weather has arrived i have noticed a new noise. During cold start engine warm up I hear a nice little tick-tick-tick which sounds to me like an exhaust leak. Is this a common problem? I have just over 58,000 miles would this be covered under powertrain or do they have some nice exclusions for exhaust?

My 1999 Ranger with 4.0 EFI V6 engine makes a "sucking sound" occasionally. At first I thought it was a belt slipping, but now I believe it is some kind of intake air leak. If I stop the truck while the sound is on, I can open my driver's door and get to about the front of the hood before the sound stops. I have never been able to observe the engine with the "sucking sound" on. Sometimes the engine will kill when the "sucking sound" stops, if the engine is idling and in gear. If I just keep driving normally, there does not seem to be any permanent problem. What the problem is?

The last couple months I have noticed what I call a "sucking" sound when driving. It is not constant and not noticeable at idle. It is more noticeable when first starting and driving for a while. seems to be getting worse and more constant. 2013 Sante Fe Sport 2.0 ...

I have a 2011 Prius, only owned it a couple of months. Today while it was idling I noticed a sucking sound coming from the gas tank. Not constant, sort of a second of suction then a second stopped, and repeat. Thought maybe the gas cap wasn't on right, opened it and closed it again, then finished driving where I was going to monitor it. The sound continued until I turned the car off. Went to try it later in the day and there was no sound, but I don't exactly trust that it's a non-problem yet.

Ok, driving home tonight from boarding (semi hard driving) car started running and shifting weird, loss of power, weird shifts in drive. At first red light I could hear a sucking sound when the throttle was pressed,or downshift tranny in manual mode. If you put the car in neutral going down the road and stab the pedal about the third time throttle will maintain 3g rpm. Babied it home, popped the hood blipped the throttle and there's def. a huge sucking sound coming from engine bay. I lightly sprayed intake/vacuum hoses/airbox etc with starting fluid and no change in idle. cant see anything loose. WTH?

Pulled out of the restaurant I ate dinner at tonight and I lost most power and there's a loud air sucking sound. I felt around all the boots and didn't feel any air, but it was really hot and couldn't feel a whole bunch. It's a 2003 7.3 with 295k. There is a little smoke/soot coming from the turbo area, any chance that's related? I'm perplexed...

Our summers typically hover in the 90's and the winters in the 40's. Each year we typically get a good cols snap and it drops in the teens at night and 20's-30's during the day.
Earlier this winter we had a week long episode of colder than normal weather which hung in the low 30's all day and teens at night.
The avg MPG's on my truck for mixed driving dropped from the 18+ that I normally enjoy to around 16.5. When the weather returned to normal for us, my MPG's returned to normal as well.
Have any of you noticed any serious climatic swings in your MPG's?
Yes, I know that vehicles normally burn more fuel in the winter but the info screen on my truck drives that point home.

I have noticed that on my 2012 5.0 Screw that the A/C isn't very cold. It is no where near as cold as my last truck, or any of a number of late model cars I have driven. If it's over 85 and I have it set to auto (70 degrees) it will never get there and just run full tilt the whole day. Even if you select Max A/C and blow it on you you will never have to turn the fan down from being cold as in other cars.

So after remotely starting my truck on a cold morning, I walk up to the vehicle and notice a small puddle of water near the middle of the truck (not near the engine where the A/C usually drips), and I can also hear a slight ticking noise that I never heard before. I stoop down and can see water dripping from the exhaust (I think off the back of the resonator?). I snap a few pics and decide I'll take a closer look later, but curiously when I return from my drive, the leak and noise are gone.
With 76K miles on the truck, is it possible I've developed a pinhole sized perforation or leak in the factory exhaust system (or maybe there's a loose fitting) that is only present when the engine is cold, but "seals" itself up once the engine is warm and the metal has expanded? I only see the water puddle and hear the noise when remotely starting the truck on cold mornings, never on warm days or after driving around town.

I have a 2011 FX4 F-150. My truck is parked in a garage at night, but obviously sits outside during the day while I'm at work. Almost every single day when it gets cold outside (probably 30 degrees or less), I climb into my truck late in the afternoon and the front brakes shutter like there's ice formation on the rotors. You can actually feel (in the pedal) and hear the rotation of that presumptive "ice" turn on the rotor and touch the pads. It usually "burns" off in just a few hundred feet, and the rest of the drive home is perfect.
BUT, sometimes that shutter is so bad that it sets off all the "check brakes", etc. type warnings on the dash. And I usually have to shut the truck off and back on to get those warnings to stop. Again, it's definitely related to the cold and there's something on the rotors or pads up front causing it. It apparently melts off almost immediately, but not before I have to use the brakes a couple of times just to get out of the parking lot, and it NEVER happens in warmer weather. The pads and rotors up front are new with lots of wear life left on them, and they are OEM Motorcraft pads.

I have a 2010 F150 with the 4.62v. I bought it new in March '11 and have used either MC 5w20 or Pennzoil 5w20 and MC filters, changing every 5k since new. When cold (30deg F or below) the right side has a loud ticking, until it has run for approx 1 minute. Since it is a 2v, cam phasers should not be a part of the problem. What the issue could be. It has just over 36k now, so the powertrain warranty should still be valid.

I posted about this back when I bought it back in Feb. and I thought the problem worked itself out but its back. When the temperature drops below 55 degrees or so, coming from the passenger side of the engine there is a chugging or knocking sound, more so when RPMs are high.
I had no issues with it all summer, but now that the temperature is dropping I noticed its back. Is this something I should worry about? What could be causing this? I had the same engine in my 07 and it never did this.

Still considering the change from my '08 F250 to a newer F150 with the EcoBoost. I have been driving as many of them as I can to get a feel for them. My current question is this: if one exhibits the dreaded rattle at cold startup, does it always get worse with more time/miles? I found another one that I'm pretty happy with overall, but it does have the startup rattle for about a second at cold start, and only at cold start. Is it worth the gamble, or should I keep looking? It's got about 108k miles and is otherwise in fantastic condition...

It's a 2011 xlt ecoboost with 14000 miles. Just started getting bad where it literally jars the whole truck. It only does it once. After I'm in 2nd then go back to 1st at a stop, it shifts fine back into 2nd. If I let it warm up for around 10 minutes or so it doesn't happen.

I have a 2010 F150 and now only cold air comes out of the vents. I have not changed the thermostat since the truck is not running hot. I have read that the blend door may be stuck. Where the blend door is on the 2010.

Experiencing blue smoke shooting out the tail pipe of your newer F150. Mine has been puffing blue since 12,000kms, still doing it at 55,000kms. Been to 2 Ford dealers (6+X) and they can never seem to repeat it. However it has been getting worse. Shop foreman guessed and said its valve seals.
I took a video, which I will post here, contacted Ford customer relations, and they tell me until it smokes at the dealer they cant go ahead with any repairs.I told Ford my truck will sit on the dealer lot until it smokes again and I am not driving it anymore. Photo is worth a thousand words, video is worth none. This is driving me up the wall!!.

Note the blue puff in the video is my truck, taken last Friday, and this is a small amount. Normally it fills my driveway and garage.
